NAME
       systemd-machine-id-commit - Commit transient machine ID to
       /etc/machine-id
SYNOPSIS
       systemd-machine-id-commit
DESCRIPTION
       systemd-machine-id-commit may be used to write on disk any transient
       machine ID mounted as a temporary file system in /etc/machine-id at
       boot time. See machine-id(5) for more information about this file.
       This tool will execute no operation if /etc/machine-id doesn't contain
       any valid machine ID, isn't mounted as an independent temporary file
       system, of /etc is read-only. If those conditions are met, it will then
       write current machine ID to disk and unmount the transient
       /etc/machine-id file in a race-free manner to ensure that this file is
       always valid for other processes.
       Note that the traditional way to initialize the machine ID in
       /etc/machine-id is to use systemd-machine-id-setup by system installer
       tools. You can also use systemd-firstboot(1) to initialize the machine
       ID on mounted (but not booted) system images.
